No. I'd log a connection from 203.36.158.121. My box would resolve this
(correctly) to scriptkiddie.fuckyou.microsoft.com but that's hardly relevant,
since IP addresses are logged and not hostnames (I've already asked for an
example of a service that only logs hostnames and people have yet to provide
it.)
xinetd logs IP addresses
ssh logs IP addresses
Linux logs IP addresses (in lastlog)
tcpd logs IP addresses (when not running in PARANOID mode and hostname
doesn't match IP address)
So, which services are we protecting?

Why should it break? Who says DNS must be correctly configured? Why do you
advocate that we should rely on DNS information at all? What's so special
about it? It's an insecure protocol that runs on (for the most part)
insecure software.

It wasn't his way of making the point, it was the point itself.
